It seems on one Orchestrator Tenant you can have either Attended Named User licenses OR Attended Concurrent User licenses! Not Both!
We plan to have both Attended Named User licenses and Attended Concurrent User licenses. We see management overhead because we will be forced to maintain two Tenants just because we plan to use both of these types of licenses.
I suggest this limitation to be removed and both these types of licenses should be allowed in 1 Tenant.
